BioThermD-™ DNA polymerase is a special purified DNA polymerase without any traces of E. coli DNA. It is optimal for the amplification and sequencing of 16S rRNA genes to identify bacteria.
One unit is defined as the amount of enzyme that incorporates 10 nmoles of dNTPs into acidinsoluble form in 30 minutes at 72ºC under the assay conditions (25 mM TAPS (tris-(hydroxy-methyl)-methyl-amino-pro-panesulfonic acid, sodium salt) pH 9.3 (at 25ºC); 50 mM KCl; 2 mM MgCl2; 1 mM ß-mercaptoethanol) and activated calf thymus DNA as substrate.
10 mM K-phosphate buffer pH 7.0, 100 mM NaCl, 0.5 mM EDTA, 1 mM DTT, 0.01% Tween 20, 50% glycerol(v/v)
Store BioThermD-™ DNA polymerase below 0ºC, preferably at -20ºC, in a constant temperature freezer.
